The change in the calls happened on the fourth night, at exactly twelve thirty-seven AM, and it was subtle enough that she almost missed it.
She had taken forty-two calls that shift. The first thirty-nine were exactly what they should have been: American voices, American problems, the specific texture of a population that had been trained by decades of customer service interactions to have very precise expectations of what the call was supposed to be. She had been graded Excellent on her last quality monitoring review, which meant she understood the form of the calls extremely well by this point — the opening, the problem identification, the solution protocol, the closing. She knew the shape of it the way a musician knows a standard — not just the notes but the feeling of the piece, the subtle dynamics of it.
Call forty was different.
The voice was American — or it was doing a very good impression of American, the flat Midwestern pronunciation, the sentence rhythms. The problem was a billing query, standard enough. She pulled up the account. Account number, customer name, billing history. She confirmed the account details. The voice confirmed them.
Then the voice asked: "What is the layout of your floor?"
Meera paused. "Sorry?"
"The floor you are currently on. Could you describe its layout to me? Approximately how long is the main walkway from the lift lobby to the pantry?"
She sat very still. Her monitor showed a billing query ticket, open, waiting for her input. The account was real — she could see the customer history, the previous interactions, everything consistent with a real account. The voice was real — the call was connected, the audio quality was normal, the background noise of a domestic American space was present, someone else talking in another room, a television faintly.
